Crawled under the truck with a flashlight to look around. Noticed driver side up pipe has some black soot around bottom of bellows, black soot on back of motor. Haven't heard any hissing or issues like others have had. No smells in cab. Truck runs strong, although I don't notice myself hitting my boost alarm much lately (set at 45psi). Other side the pipes look fine. Am I doomed? Is it gonna kill the truck to run it till it gets worse? I would have never known if I hadn't looked. Now I wish I wasn't so nosey.

I just got under mine yesterday and my drivers side bellow is blown... I heard large exhaust leakage though before i noticed. Probably been cracked for a while... You'll def. be able to tell when it reallly blows out. Super loud leak under load and increased egts is what I noticed. Mine is parked until I get it in at a shop. Deciding what all I want to do while its in there. Def. going with 6.0 manifold and up pipes.

Yeah from what I'm reading it looks like the way to go. I would prefer to do everything one time if possible. I'm thinking what you said, plus studs while the cab is off. Gaskets aren't popped yet, but my luck they will if I don't do it now. I have an early 08. Wonder if they can fix that wiring harness issue for the HPFP while they are in there. I'm not really sure what else to do. I don't race, and don't want to do injectors/nitrous or any of that stuff. I'm just planning on 500-550 reliable power on stock fuel. It's my daily driver. Highest tunes I run are xtreme street/hot street. Any suggestions are appreciated!!

Yeah I'm with ya. Mine is an early 08 also. Had my HPFP replaced already so I'm hoping they upgraded the harness when they did that job, but i doubt it. I'm debating on studs... Really debating on dropping in a 71mm atmo... Dont think I will but I want to haha. I'll see what kind of estimate I get for doing the manifolds and up pipes and decide what I want to add from that.

Could if just your egr crossover pipe was blown... Mine is the actual drivers side off the manifold...

Mine too. Guess it doesn't matter for me anyways, cab is coming off. Since it's off we will do up pipes, studs, rockers, and that upgraded HPFP harness. Hopefully there's no hidden issues we will find while cab is off. I'm at the end of my budget. Just trying for reliability. I don't really want more power than a hot tune and deletes will give me anyways. I won't even really run a race tune unless I find out it gets better mileage.

How many miles do you have? Those sound like good things to do while the cab is up. Check out the heavy duty up pipes from darkhorse diesel. You shouldn't have to worry about it anymore after this. Another thing you may want to consider are both idler pulleys and belt tensioners depending on mileage. Its not necessary but much easier to replace while the cab is up

85K miles. Was kinda waiting for a reason to pull the cab to do the studs and other upgrades. Will check into those pulleys, and anything else we see once cab is off. Thanks for the suggestions, I will definately check out those up pipes.....
